DVOC Field Trip Report
by Denis Brennan

October 24, 2010
John Heinz National Wildlife Refuge at Tinicum, PA

The DVOC met at 8.00 am Sunday for a field-trip to the John Heinz NWR. There were five members and four guests. We were joined by the regular walk at Tinicum at 9 am that included ten more guests when there was a mix up in the refuge's schedule. Inviting the people to join us was a great way to introduce the Delaware Valley Ornithological Club to the public. This was a large group so Lynn Roman agreed to help me co-lead the field-trip. We made our way to the frog pond, the boat landing, Warbler woods and across the large board walk to the observation tower. We birded our way back to the parking lot and finished up at noon. The great weather rose to 70 + degrees. Our group saw 44 species of birds.
